Due to how guard skill cooldowns are shared you can cast Molten Shell constantly without risking removing your Vaal Molten Shell buff, because if you do so Molten Shell will never be off cooldown while Vaal Molten Shell is active.
• Order of Operations: Guard skills happen after all other mitigation when receiving damage, so your character always takes 65-70% of damage directly to their base resources (ward, energy shield, life, mana). To reach the damage cap of a level 20 gem, the character would need to heal (.65/.35*30000=) 55714 points of the affected resource(s) over the buff's duration.
• Soul Gain Prevention is only applied after the buff effect is calculated, so the modifier ChosenChosen
  Prefix
  +(3201-4000) to Armour during Soul Gain Prevention will grant additional Armour during and after the skill's effect, but the added Armour will not be taken into account when calculating the buff's damage absorption.

Strategy

Unlike its non-Vaal counterpart, Vaal Molten Shell will persist for the full duration, regardless of how many times an explosion is triggered. This unique property offers potentially vastly more utility than Molten Shell at the cost of less availability. Because of this, it is recommended that Vaal Molten Shell be saved for an occasion in which it will offer the greatest benefit, such as during an encounter with a unique monster or even a troublesome rare.

Due to the nature of Vaal Molten Shell, it has synergy with support gems that utilize the potentially frequent explosions, such as stun or life leech; however, the rather steep soul cost of Vaal Molten Shell gates the strength of the gem. In addition, while the armour offered during Vaal Molten Shell's duration is first-rate, it may cause conflicts with Cast when Damage Taken SupportCast when Damage Taken SupportSupport, Spell, Trigger
